Newbie Question about workpiece holding

[Faust]

I think most people would cut it without turning it over. You just need a long enough tool and depth increments suitable for your machine.

So clamp from the top, cut in between the clamps, then move them around and cut the bits that were covered? This seems prone to error and it's what I want to avoid. Or do you mean cutting the perimeter last and trusting the newly-disconnected piece not to chip or go flying off?

Besides, I'll have to turn it over sooner or later as there will be designs on both the upper and lower face.
